State and local government employers across the state are borrowing from the state pension system to finance the contributions they owe to that same system. The state comptroller's office, which cooked up this unusual arrangement in 2010 along with then-Gov. David A. Paterson, says it is less a matter of borrowing than it is a form of amortization, in which debts are paid gradually, with interest.

This benign description is an exercise in self-deception. Debt is amortized by paying down the balance. The balances owed to the pension system in New York continue to mount rapidly as cash-strapped budgeters take advantage of the liberties they are being offered.

In the past year, the number of public employers using the borrowing scheme has tripled. This fiscal year, municipalities are handing over IOUs for around $200 million, while the state itself is borrowing $553 million. Next year, borrowing from the pension fund may exceed $1 billion. The only thing being amortized is confidence in the New York pension system's integrity.

The program's defenders claim that amortization is necessary to smooth out the effects of market volatility and tax revenues that fluctuate along with economic conditions. "Amortizing pension costs is an option for some local governments to manage cash flow and to budget for long-term pension costs in good times and bad times," state Comptroller Thomas DiNapoli said in a statement.

But there's a big problem with this gamble. There's no way of ensuring that the pension fund's investment performance will quickly improve, or that public employers will have the cash they don't have now at some point in the reasonably near future. Given that these municipalities and institutions are already unable to keep current on their existing contribution burdens, it seems overly credulous at best, and just plain dumb at worst, to hope they will soon be able to fund not only the new obligations they rack up, but also the contributions they're now deferring, plus interest. Meanwhile, it is 100 percent certain that pension costs will ultimately need to be paid.

The underlying problem in New York is the same as in many other cities and states: For years, public employers have made promises they simply can't afford to keep.

There are a number of ways to postpone dealing with the issue. While New York devised its dubious amortization program, Illinois and New Jersey have issued bonds to push costs into the future. There are, however, only two real solutions to the underlying problem. States and municipalities can cut pension costs by reducing benefits, or they can cut pension costs by reducing their workforces.

In New York, Gov. Andrew M. Cuomo has made a set of proposals for ways to start cutting costs. Under his plan, the retirement age would increase from 62 to 65; new employees would be required to contribute 4 to 6 percent of their salaries to pensions, as opposed to the current standard of 3 percent; and an alternative 401(k)-style retirement plan would be offered to new employees.

While Cuomo's plan is being treated as a radical call for reform by supporters and critics alike, it actually does not go far enough. To truly fix New York's pension problems, Cuomo would need to insist on making the new 401(k)-style plans mandatory for new employees, rather than just offering them as a voluntary option. It's also no longer feasible to maintain the current pension system for existing employees without cutting their numbers; the fact that governments already cannot meet their current obligations is proof of that. The state and its municipalities need to switch current employees over to the new 401(k)-style plans, require them to contribute more of their salaries, or significantly reduce the number of workers accumulating benefits.

Yet even Cuomo's relatively modest proposals may not get much traction. Public employee unions continue to exert an outsize influence. In New York, they have a strong ally in Comptroller DiNapoli - the man who is supposed to serve as the state's fiscal watchdog. DiNapoli has essentially promised to do everything in his power to block Cuomo's plan, telling the state's Conference of Mayors, "I may not have a vote in this, but I do have a voice in this."

Meanwhile, public employers in New York continue sinking deeper into debt. "The threat of bankruptcy hangs over every single municipal government in the state because of escalating pension costs," Maggie Brooks, the county executive of Monroe County, said. That is no exaggeration.

Most municipal officials seem fully aware that borrowing from the pension fund to pay the pension fund is no solution, but they see no other choice. "I don't think any financial manager likes to see the can kicked down the road," Tamara Wright, the comptroller of Southampton, told The New York Times. But nevertheless Southampton, on the East End of Long Island, borrowed a fifth of its pension bill this year. As long as municipalities can avoid facing the full costs of the pension obligations they're incurring, we are unlikely to see any real effort to fix the underlying problems.

As Thomas M. Roach, the mayor of White Plains, put it: "The road to hell is paved in amortizing pensions."
